Rainfall intensity duration frequency curve statistical analysis and modeling...bijceesjournal
Using data from 41 years in Patna’ India’ the study’s goal is to analyze the trends of how often it rains on a weekly, seasonal, and annual basis (1981−2020). First, utilizing the intensity-duration-frequency (IDF) curve and the relationship by statistically analyzing rainfall’ the historical rainfall data set for Patna’ India’ during a 41 year period (1981−2020), was evaluated for its quality. Changes in the hydrologic cycle as a result of increased greenhouse gas emissions are expected to induce variations in the intensity, length, and frequency of precipitation events. One strategy to lessen vulnerability is to quantify probable changes and adapt to them. Techniques such as log-normal, normal, and Gumbel are used (EV-I). Distributions were created with durations of 1, 2, 3, 6, and 24 h and return times of 2, 5, 10, 25, and 100 years. There were also mathematical correlations discovered between rainfall and recurrence interval.
Findings: Based on findings, the Gumbel approach produced the highest intensity values, whereas the other approaches produced values that were close to each other. The data indicates that 461.9 mm of rain fell during the monsoon season’s 301st week. However, it was found that the 29th week had the greatest average rainfall, 92.6 mm. With 952.6 mm on average, the monsoon season saw the highest rainfall. Calculations revealed that the yearly rainfall averaged 1171.1 mm. Using Weibull’s method, the study was subsequently expanded to examine rainfall distribution at different recurrence intervals of 2, 5, 10, and 25 years. Rainfall and recurrence interval mathematical correlations were also developed. Further regression analysis revealed that short wave irrigation, wind direction, wind speed, pressure, relative humidity, and temperature all had a substantial influence on rainfall.
Originality and value: The results of the rainfall IDF curves can provide useful information to policymakers in making appropriate decisions in managing and minimizing floods in the study area.

Electric vehicle and photovoltaic advanced roles in enhancing the financial p...IJECEIAES
Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network
Advanced control scheme of doubly fed induction generator for wind turbine us...IJECEIAES
This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

5. Basic GSM network (1)
• Driving idea in GSM: to define several open interfaces.
– Operator may obtain different network components form different suppliers.
– Strictly defined interface determines how the functions are proceeding in the network
and which functions are implemented internally by the network element.
• GSM provides a means to distribute intelligence in the network. Network
divided into four subsystems:
• Network Subsystem (NSS): call control.
• Base station Subsystem (BSS): radio path control.
• Network Management Subsystem (NMS): operation and maintenance.
• Mobile Station (MS).
• Difference between 1G and 2G:

service logic instances are permitted to interact with basic call and connection
control capabilities.
• Point In Call (PIC) identify CCF activities required to complete one or more
basic call/connection states or interest to IN service logic instances.
• Detection Point (DP) indicate points in basic call and connection processing at
which transfer of control can occur.
• Transition indicate the normal flow of basic call/connection processing from
one PIC to another.

application which manages the credit).
– provision of services to users or groups of users.
• Request:
– version of specific services supported in serving network and terminal.
– details (e.g. protocol versions and API versions) of available service capabilities supported in
the serving network, and terminals.
• Handle charging for services.
• Inform the serving network:
– of the type of charging (i.e. prepaid or/and postpaid) for any required service.
– of the threshold set for a given service required by the user and charged on a prepaid account.
– how to manage a service for which the threshold has been reached.
• Deploy services to users or groups of users.
39. Serving Network requirements for VHE
provision
The serving network should not need to be aware of the services offered via the
home environment.
It shall be possible for the serving network to perform the following:
• The serving network shall support user access to services in the home
environment.
• The serving network shall provide the necessary service capabilities to support
the services from the home environment as far as possible.
• Dynamically provide information on the available service capabilities in the
serving network.
• Provide transparent communication between clients and servers in terminals
and networks.
• Request the charging information (type of charging, threshold for prepaid
services and behaviour if the threshold is reached) for any service possibly
required by the user.
• Handle the call according to the instructions received by the home
environment regarding charging activities.
• Inform the home environment of the chargeable events.
